Abstract

THE INVENTION RELATES TO A PROCESS FOR THE PREPARATION OF A POLYPROPYLENE FOR E.G.PIPE, PROFILE AND MOULDING APPLICATIONS, CONTAINING FROM 1.0 TO 10.0BY WEIGHT OF ETHYLENE OR C4-C10-(ALPHA)-OLEFIN REPEATING UNITS AND HAVING A MFR2 VALUE OF BETWEEN 0.05 AND 0.40 G/10 MIN BY POLYMERIZING PROPYLENE AND ETHYLENE IN THE PRESENCE OF A CATALYST SYSTEM, THE PROCATALYST COMPONENT OF WHICH IS A REACTION PRODUCT OF AT LEAST A TETRAVALENT TITANIUM COMPOUND AND A MAGNESIUM HELIDE COMPOUND AND THE COCATALYST COMPONENT OF WHICH COMPRISES AN ORGANOALUMINIUM COMPOUND, AND HYDROGEN AS A MOLECULAR WEIGHT REGULATING AGENT, TO GIVE SAID POLYPROPYLENE. THE CREEP-RESISTANCE OF THE POLYPROPYLENE IS IMPROVED BY PERFORMING THE PROCESS BY MEANS OF THE FOLLOWING STEPS:(A)COPOLYMERIZING PROPYLENE AND ETHYLENE INTO A RANDOM COPOLYMER AT 40 TO 110°C USING: A CATALYST SYSTEM OF THE ABOVE-MENTIONED TYPE; A PORTION OF ETHYLENE OR C4-C10-(ALPHA)-OLEFIN LEADING TO 1.0 TO 10.0BY WEIGHT OF ETHYLENE REPEATING UNITS IN SAID RANDOM COPOLYMER; AND NO OR A MINIMAL AMOUNT OF HYDROGEN LEADING TO A MFR10 VALUE OF BETWEEN 0.01 AND 5.0 G/10 MIN FOR SAID RANDOM COPOLYMER, IF THIS STEPS IS PERFORMED FIRST, OR TO A MFR2 VALUE FOR SAID POLYPROPYLENE OF BETWEEN 0.05 AND 0.40 G/10 MIN, IF THIS STEP IS PERFORMED AFTER STEP (B); THE PROPORTION OF RANDOM COPOLYMER OF THIS STEP BEING FROM 20 TO 80BY WEIGHT OF SAID POLYPROPYLENE,(B)POLYMERIZING PROPYLENE AT 40 TO 110°C USING : A CATALYST SYSTEM OF THE ABOVE-MENTIONED TYPE; NO OR A MINIMAL PORTION OF ETHYLENE LEADING TO 0.0 TOBY WEIGHT OF ETHYLENE REPEATING UNITS IN THE POLYMER RESULTING FROM THIS STEP; AND AN AMOUNT OF HYDROGEN LEADING TO A MFR2 VALUE OF BETWEEN 30 AND 300 G/10 MIN FOR SAID POLYMER, IF THIS STEP IS PERFORMED FIRST, OR TO A MFR2 VALUE FOR SAID POLYPROPYLENE OF BETWEEN 0.05 AND 0.40 G/10 MIN, IF THIS IS PERFORMED AFTER STEP (A); THE PROPORTION OF POLYMER OF THIS STEP BEING FROM 80 TO 20BY WEIGHT OF SAID POLYPROPYLENE. THE POLYPROPYLENE CAN BE ELASTOMER MODIFIED BY:(C)PROVIDING AN ELASTOMER, THE PROPORTION OF WHICH IS FROM 5 TO 40BY WEIGHT OF SAID POLYPROPYLENE. IN THIS CASE THE MFR2 VALUE OF THE POLYPROPYLENE CAN BE FROM 0.05 TO 50 G/10 MIN.
